1：新建目录：
2：下载Mysql数据库文件：
wget https://downloads.mysql.com/archives/get/p/23/file/mysql-5.7.39-1.el7.x86_64.rpm-bundle.tar:
3：安装数据库文件
解压文件
tar -xvf mysql-5.7.39-1.el7.x86_64.rpm-bundle.tar
yum -y install mysql-comm*.rpm
按照过程中发现包冲突，由于是新装的系统，故卸载掉相关包，重新安装
rpm -qa | grep mariadb
rpm -e --nodeps mariadb-connector-c-3.1.11-2.oc8.1.x86_64
rpm -e --nodeps mariadb-connector-c-config-3.1.11-2.oc8.1.noarch
再次执行安装
yum -y install mysql-comm*.rpm
安装成功

[root@VM-4-14-opencloudos mysql]#
执行mysql重启
systemctl restart mysqld.service systemctl start mysqld.service systemctl stop mysqld.service
查询启动过程的随机密码
cat /var/log/mysqld.log | grep 'temporary password is generated'
重置密码：
登录Mysql
mysql -uroot -p ALTER USER 'root'@'localhost' IDENTIFIED BY '123456@abcAbc';
由于上述密码策略不能设置简单的密码，故设置复杂的，开发及测试环境想要容易记得点，故设置简单的密码
修改密码后，查询密码策略等级
show variables like 'validate%';
SET GLOBAL validate_password_policy=LOW set global validate_password_length = 6
设置远程登录MySQL
允许root用户在任何地方进行远程登录，并具有所有库任何操作权限；
GRANT ALL PRIVILEGES ON *.* TO '你的账户'@'%' IDENTIFIED BY '你的密码' WITH GRANT OPTION; flush privileges;
如果无法本地登录，可以查看防火墙或者ACL访问控制是否限制了端口
Linux防火墙
firewall-cmd --state systemctl stop firewalld.service systemctl start firewalld.service systemctl disable firewalld.service systemctl enable firewalld.service
云服务器ACL配置：
测试联通并访问成功：
